Can I update SpywareGuard manually?

I haven't been able to use the Live Update function lately although I could perform it before. When I perform Live Update on SG, I receive Error and fail to connect to the server where the updates should be. If I can manually download updated data files for SG like for SB, please let me know where and how to do.

Incidentally, I haven't been able to check for updates on SpywareBlaster and AVG lately either, although I can search for and download updates on Ad-aware and Spybod. I use Windows XP Home Edition Version 2002 Service Pack 1, and AOL 9.0 on the dial-up connection, and don't use personal firewall software. Is there anyone else that has the same problem?
